Hmm ... but nothing for the old-fashioned plain blessed packages?..
I think you can do better (for example recurse into the classes @ISA, and filter out methods beginning with an underscore (which are private by convention), DESTROY etc.), but there are conceptual limits.
Perl doesn't have different declarations for subs and methods, so it's impossible to distinguish these two automatically.
Maybe there are better solutions to your problem. For example the thread Runtime introspection: What good is it? discusses (among a variety of other things) possible alternatives to to introspection.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
